Description
Test Principle: This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to PI has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled PI and unlabeled PI (Standards or samples) with the pre-coated antibody specific to PI. After incubation the unbound conjugate is washed off. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of PI in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of PI in the sample
